Im looking at getting this DAC/amp and getting a pair of grado 225s which have an impedence of 32 ohms. Will they work well together. Or is 32 too low

This answer may be 9 months too late but for those thinking of purchasing this product in the future, yes it will work but you will not see a great difference vs not using an amp since even most smartphones can drive 32ohm headphones decently.

I have a hyfonics 3200.1 at 1ohm pushing these. It's turned down to push the speakers without blowin them of course. I'd say your probably fine with that amp. Remember if you get a bigger amp than needed it will operate much cooler than getting a amp and having to turn it up all the way to push them. I recommend getting something a little bigger and tune it accordingly.

The the lower the ohms the MORE volume you have. So 24 ohms will be a bit louder than 32 ohms, you could a one time buy headphones with a 16 ohms. But now most headphones are 32 ohms. T. Smith has given you the wrong answer. Anyone else want to confirm this?

I had these paired with the Hifiman EF5 hybrid amplifier which drove it sufficiently, but since these cans have low impedance there're better matched with solid state amplifiers or hybrids rather than pure tube amps. Low impedance cans like these require more current in which solid state amps posses rather than the high voltage produced by tube amps.

Absolutely id wire them in parallel. I have my two in a 4 cubic foot of tuned at 32hz ran with a hifonics Brutus 2000.1 wired at 2ohms and it impresses a lot of people. So you will love them especially with more power.

Oh yes, they should give you all the volume you can take. From the start they sound great and then get even better as they break in. Just keep in mind that their impedance is 8 ohms.

They work fine. The impedance is 32 ohms or something. That's supposed to work okay with standard modern headphone jacks (like on a portable digital music player or laptop)

You need to look at the OHM number. This has a high one. I'd search for a much lower impedance number for portable use. These cans are amazing but they need something to power them with more oomph than an iPod. For portable use, I use a pair of Pioneer HDJ 1500's with an impedance rating of 32 OHM. I cherish these Koss headphones but they can't possibly sound good hooked to an iPod and they probably would chew through the battery regardless. That said, buy them anyway! Everyone should own a pair of these beauties.

For more bass, you definitely want less resistance with the 2 ohms. Just make sure the rms is correct for it. You want to get all you can out of the amp.

Four speakers (2 pair) at once yes. Four pairs no. Total resistance should not drop below 4 ohms with most amplifiers.

I'm running infinity kappa components which are 2 ohm and they work and sound awesome. I do recommend running a solid 4 channel amp but its not required.

I don't see why not? I'ts only 2 ohms below 8 ohms. A little bit harder to drive those BS41's but yes, you can; particularly if you're just using these speakers for surround.

I'd stick with the same. Some amplifiers can operate "unsafely" I.e. overheating or crappy sound, if they can't produce the right impedance per whatever ohm each speaker has. I'd start from ground up if you're wanting bigger better sound

Yes definitely. M50 has an impedance of 38 ohm but those "unprofessional" music output are mostly designed for earphones less than 32 ohm (preferably 16 ohm). If you're using a DAP such as DX90 instead of an iPod for M50, you'll notice that the player has better control of the music, more detail, bouncy and more punchy but at the sometime precise bass (drums). This is my experience as I have the same equipment you have.

Anything can be blown, judging on te name brand I your amp you should have enough for a couple of these, for best sound run them separate on the amplifier at 4 ohms

It will work, but I couldn't find the output impedance so I don't know how well it will work. I use mine with an HT Omega eClaro which has an output impedance of 8 ohms. I notice a difference between these with 50ohms resistance compared to my beyer 900 pros which are 250ohms.

The manual specifies 6 ohm or higher. Mine are 8 ohm and work well with this amplifier. I don't know how well 4 ohm speakers would work.
